CNC Build Club – Gonzo Build #2

One Axis Drawing Machine

This week the CNC Build Club is going to attempt Gonzo Build #2.  A gonzo build is where we try to knock out a complete CNC project in one night.  Gonzo build #1 was the Quantum Delta 3D printer.

This week we are going to build a one axis 2D drawing machine.  This uses two independently controlled carriages on the same axis to get 2D motion at the ends of the linkages.  The purpose is only to have a little fun and to cut our teeth on a simple inverse kinematics machine before moving onto a much more complex 6 axis machine.

If you want to help, please join us.  The meeting is open to non members.  Please RSVP via meetup.

Bitbeam Presentation – CNC Build Club

Bitbeam

This week we have a presentation by Jason Huggins (@hugs) on Bitbeam and the Tapster robot he built with it.

jason-huggins-with-tapster

When:

Thursday, May 9th @ 7:00pm, upstairs in the electronics area

Topic:

Jason will give an overview of Tapster, his open source, 3D printable, mobile app testing robot. In addition to explaining why creating a mobile testing robot is not the worst idea you’ve ever heard of, Jason will give an overview of Bitbeam, the open source building toy that he developed, which Tapster’s made out of. He’ll cover his making journey as he’s experimented with laser cutters, CNC mills, and 3D printers to make Bitbeam. For fun, the talk will also include live demos of Tapster playing Angry Birds.

About Jason:

Jason Huggins is CTO and co-founder of Sauce Labs, a software test infrastructure company, and is the original creator of Selenium, a popular open source web testing tool. In 2011, for an art project he was working on, Jason created Bitbeam – a 3D printable LEGO-Technic-compatible construction toy. Jason lives in Oak Park, Illinois.

CNC Stuff

Following the presentation we will break away to work on various CNC projects. The ongoing group project continues to be the mid-sized CNC Router. The machine is now fully functional under Mach3 control. We can talk about the Mach3 setup and cut a few things.

Last Night’s CNC Build Club

DSC00514

We had a great meeting last night.  We had over a dozen people working together to wire up a CNC control box.  At one point we had three soldering irons going at the same time.  Here is the pile of parts we started with.

Starting Pile Of CNC Parts

 

Here are some people wiring the box.  A really nice job was done using wire ferruls wherever we could.  How many hands can fit in that little box?

Here is the nearly completed box.

Box Almost Done

 

Thanks to Chris, Matt, Aeva, Patrick, Donald, Steve, Jason & Alex, Cat, John, Will, Gabe, Norm, Allen and Colin.  Next week we will be testing the motors, adding limit switches and configuring the software.

We will start with Mach3, then switch to EMC2 when we find a dedicated PC for that.  Chris and John I think mentioned they do time at Free Geek.  I am sure they could find a little PC.

Special thanks to Automation Technologies Inc for giving/lending all the parts.

CNC Build Club

Automation Technologies 3D Gantry

The CNC Build Club meets just about every Thursday at 7:00pm.  This is a weekly meeting of Chicago area people passionate about designing, building and learning how to use digital fabrication equipment.  Non members are welcome .  Each meeting starts with a round robin introduction followed by a little discussion and often a presentation or training session.  We also often have a group project going on.

This week we are going to start putting together a small CNC milling machine.  The machine was lent to us by Automation Technologies Inc.  Right now the machine is just the mechanical platform.  We need to add the motor controls, limits switches and setup some software.  The goal is to create an easy to use work center that we will do some projects on.  The plan is to sell the machine at a discount to someone in the group when we are finished. If you don’t know anything about CNC, don’t worry, you can still help.  The goal is to teach, learn and use.

Pictures from the Scanning Electron Microscope

A few nights back, Brian and I took some images from the SEM. We exported them into TIF format, and then copied them via Sneakernet, a.k.a. using 3.5″ floppy disks and a portable USB floppy reader. I converted them into .png files. Click them for full 1024×768 resolution, the limit of the Leica image capture board. I’m very happy with how they turned out.

NERP tonight! Eric Stein: RPi hardware i/o and ZeroMQ

ERP is not exclusively raspberry pi, the small computer and embedded control interest group at Pumping Station:One in Chicago.

Tonight, Eric Stein, who is Chief Cat Herder and president of Pumping Station:One will take time out of his busy schedule to show us a Raspberry Pi and Python based system that sends messages by passing messages.

eric-beer-240
Eric’s system, which is currently in development, receives input from IRC (internet relay chat) and responds by playing an informational message over one of several louudspeakers located around the PS:1 facility. The Pi does text-to-speech conversion on stored messages and i/o logic and control to select the appropriate audio output channel.

A very interesting aspect of the system is the use of ZeroMQ to pass control messages between the Pi and and a server that does something important that Eric will explain. From wikipedia:

“ØMQ (also spelled ZeroMQ, 0MQ or ZMQ) is a high-performance asynchronous messaging library aimed at use in scalable distributed or concurrent applications. It provides a message queue, but unlike message-oriented middleware, a ØMQ system can run without a dedicated message broker. The library is designed to have a familiar socket-style API.”

Beer Church: Beer Tasting, Sunday April 7th, 2PM

Hello everyone!

Since the last Beer Church, Eric & co’s This Is Your Grain On Chocolate has come and (sadly) gone. We’ve got 5 different Beer Church creations hidden away in bottles, and they’re all coming out to play this Sunday. Bring them some playdates in the form of a bottle of your favorite off-the-beaten-path beer – whether your own homebrew, or from a store. We’re not picky (but we are snobs)! Small beer steins will be provided to consume from, but you’re welcome to bring your own chalice.

Once we’re done with the tasting, Eric will demonstrate how to use a Soxhlet Extractor to create flavor extracts from a fruit or herb (undecided yet) – so far, we’ve used 2 of them – in our dearly departed friend, This Is Your Grain On Chocolate.

After we taste & make some flavor, we move forward to build out fun time. Our current fermenter was built hastily to get us off the ground and we’re going to try to get started replacing it with a better designed and larger home for brews. Chillmon has a new circuit board courtesy of Ryan, and we might find the time to get it working with the new fermenter. Along the way, we’ll figure out a superior storage solution for our gear (this time, with organization!). No brew today, but we’re hoping for a productive and fun day of woodworking, tasting beers, electronics, programming, and tasty science.

tl;dr

When: Sun April 7, 2:00PM-5:00PM
Where: Pumping Station: One, 3519 N Elston, Chicago
Why: Because you like tasting beer & building things
What: Potluck & Beer Church’s brews beer tasting, Buildout
Extra Credit What: Demonstration of Soxhlet Extractor flavorant creation for use in beer making
Who: Anyone 21 years or older

Scanning Electron Microscope Update

SEM and RyanBack in January, we got word that Philip Strong, a past member of PS:One, worked for a company that needed to get rid of a working scanning electron microscope and was considering donating it to PS:One. While we have an existing SEM in the space (a Leica S440, owned by JP, a member), this one supposedly was fully functional, had documentation, and we could get some help from the microscopist, Susan Young, who used it. Of course we were interested!

On Monday the 18th, I learn that yes, the donation was approved, but with a catch: It had to be moved on Saturday the 23rd! Read the rest of this entry →

Boardforge gantry Ver 0.3a in development (Ed_B)

Several members of Pumping Station:One are collaborating on a project to produce a pick and place machine. PnP machines are robotic assembly devices that place electronic components on circuit boards as part of the soldering process. The software that will run the machine is made of several distinct subsystems including motion control and computer vision. Jay Hopkins has been doing some experiments to determine whether a Raspberry Pi can serve as the on-board controller for the machine. Tonight he’ll show nerp some of his progress. Teaser: OpenCV _will_ compile on the Raspberry PI!
